Hi @Fox @Carlos according to this thread you posted about him, Fatid's trait is Tough. In the game monstagram entry and on the wiki it shows mountain though.
Which is going to be his final trait?
Tough makes him withstand better vs all the ranked Laomu's possession in Nature and vs Underworld and Evil possessors, but makes him more vulnerable to Talika for example.
While Mountain, eventhough is better vs stunners and freezers like Talika in nature and Krampus in evil, leaves him more open to possession and torture effects.
